How to choose
Suction for carpet fibers
Suction in pascals is the headline number for carpet: the DREAME and roborock list 20,000 Pa, the iRobot lists 15,000 Pa and the Airzeen lists 6,000 Pa. The DREAME pulls dust and pet hair from carpet fibers, and the roborock boosts suction on carpets. Compare the pascal figure with the carpet features before you choose.
Self-emptying and run time
A self-emptying dock sets how much you touch the dust: the DREAME holds up to 120 days in a 4 L bag, the iRobot up to 90 days in a 2.5 L bag, and the Airzeen up to 45 days in a reusable cup. Run time sets how much floor one charge covers: the roborock runs 253 minutes, the iRobot 173 minutes, and the DREAME and Airzeen 150 minutes each. Weigh dock capacity against run time for your home.
Mopping and carpet care
All four picks mop as well as vacuum, so carpet care comes down to how each one handles rugs. The iRobot sets a No Mop Zone so rugs stay dry, the roborock removes the mop and lifts its module up to 15 mm, and the Airzeen asks you to remove the mop holder before carpet cleaning. Check the mop controls before you run it over rugs.
